Double‐chambered left ventricle (DCLV) is a particularly rare congenital entity characterized by the presence of two ventricular cavities separated by an abnormal muscle band. An asymptomatic 15‐year‐old boy was referred to our hospital because of electrocardiographic (ECG) abnormalities. His initial transthoracic echocardiography (TTE) demonstrated a DCLV with mild left ventricular systolic dysfunction. During a 5‐year follow‐up period, he remained symptom free with no changes in ECG and conventional TTE findings. However, two‐dimensional speckle tracking echocardiography revealed a subtle progressive deterioration of left ventricular systolic function during the 5‐year follow‐up.
